PREMASGARD ® SHD 652
The pressure sensor ⁄ differential pressure sensor PREMASGARD
®
SHD -652 is used for
pressure measurement in gaseous and liquid media. It converts the measurand into standard
signals of 0 -10 V. Process connection is 2 x G 1 ⁄ 8 " straight internal pipe thread. PREMAS-
GARD
®
SHD -652 differential pressure transmitters are applied in piping and hydraulic sys-
tems, in mechanical and plant engineering as well as in building automation.
Not applicable for ammonia and Freon !
